Double Worm Slewing Drive WED17

What is Double Worm Slewing Drive WED17?

The Double Worm Slewing Drive WED17 is an advanced and highly efficient mechanical component designed to provide reliable rotational motion for a wide range of heavy-duty applications. This slewing drive features a unique design where two worms drive a single worm wheel simultaneously, resulting in significantly increased output torque and holding torque. The WED17 slewing drive is known for its compact design, high performance, and robust functionality, making it an ideal solution for applications where space is limited, but high torque and reliability are essential.

This drive system is often used in large-scale machinery, particularly in industries that require high levels of torque and precise rotational motion, such as construction, mining, and heavy equipment. The WED17 design allows it to operate effectively under extreme conditions, including high load environments, while offering self-locking capabilities for enhanced safety. It also provides superior durability and efficiency, contributing to the overall performance of the machines it powers.

At its core, the WED17 slewing drive is made up of three primary components: the base, the worm gears, and the worm wheel. These components work together in a sealed protective casing, capable of withstanding axial, radial, and tilting forces simultaneously. This unique feature makes it an ideal choice for systems that need to withstand high mechanical loads, ensuring safety and longevity even in harsh working environments.

The key to the WED17's success lies in its ability to combine the best features of traditional slewing drives with modern engineering advancements, delivering a product that is not only highly effective but also incredibly versatile in a variety of settings.

Features of Double Worm Slewing Drive WED17

The Double Worm Slewing Drive WED17 is packed with features designed to optimize its performance, efficiency, and durability. Below are the standout features of this slewing drive:

1. High Output Torque and Holding Torque
   The WED17 offers impressive output and holding torques, which significantly increase the mechanical performance of any system. With an output torque of 9.45 kN·m and a holding torque of 108.5 kN·m, the WED17 ensures reliable and powerful operation, even under heavy loads and harsh conditions.

2. Self-Locking Functionality
   One of the most valuable features of the WED17 is its self-locking capability. In the event that the driving power is lost, the slewing drive prevents the rotation components from reversing. This safety feature ensures that the system remains securely locked, preventing unwanted movement and enhancing the safety of the entire system, especially in high-risk environments.

3. Compact and Robust Design
   Despite its high torque output, the WED17 maintains a compact and robust design. It is engineered to provide exceptional performance while fitting into installations with the same mounting dimensions as the WE17 series slewing drives. This makes the WED17 a versatile choice for applications where space is a concern but high torque is still required.

4. Precision and Reliability
   The WED17 features an impressive tracking precision of ≤0.1°, ensuring highly accurate and repeatable rotational motion. This precision is critical for applications that demand tight control over movement, such as heavy-duty cranes, turntables, and rotating platforms.

5. Sealed Protective Design
   The slewing drive is sealed with a protective casing that allows it to function in environments that are exposed to moisture, dust, and other environmental factors. This sealing ensures that the internal components remain safe from corrosion, wear, and other damaging elements, making the WED17 suitable for both indoor and outdoor use.

6. Dual Row Ball Bearing
   The WED17 uses a dual-row ball bearing (eight-point contact ball series) in the design, which enhances the bearing capacity and improves the drive's performance in heavy-load situations. This bearing type increases the axial load, radial load, and tilting moment capacity, making it ideal for applications like heavy machinery and industrial equipment.

7. High Load Capacity
   The WED17 is built to withstand high axial and radial loads. The axial static rating of 1166 kN and the radial static rating of 435 kN ensure that the slewing drive can handle extreme forces without compromising its integrity or performance.

8. Adaptable Gear Ratio
   The WED17 features a gear ratio of 104:1, offering a balance between speed and torque for various applications. This gear ratio can be tailored depending on specific operational requirements, providing flexibility in its use across different types of machinery.

Applications of Double Worm Slewing Drive WED17

The WED17 Double Worm Slewing Drive is designed for a wide range of applications across several industries. Its robustness, high torque output, and self-locking functionality make it an ideal choice for heavy-duty machinery that requires precision and reliability. Below are some of the most common applications:

1. Construction Equipment
   Heavy-duty construction machines like cranes, excavators, and earth movers require slewing drives that can handle massive amounts of torque while ensuring precise rotational movement. The WED17 is used in the rotation mechanism of these machines, enabling them to lift, move, and rotate heavy loads with ease.

2. Marine Applications
   The WED17's excellent sealing capabilities make it an ideal choice for marine applications, such as ship cranes, winches, and offshore platforms. It can operate reliably in harsh marine environments, resisting water ingress, salt corrosion, and high humidity.

3. Heavy Machinery
   In industries like mining, steel production, and industrial automation, the WED17 is used in the rotation mechanism of large machines, such as rotary kilns, turntables, and other rotating industrial equipment. Its high axial and radial load capacity allows it to endure the demanding conditions of these industries.

4. Wind Turbines
   The WED17 is also used in wind turbines, where it controls the rotation of the nacelle to optimize the turbine's exposure to wind. The self-locking function is particularly valuable in preventing unwanted movement when the wind speed changes, ensuring stability and safety.

5. Aerospace and Defense
   In aerospace and defense applications, the WED17 is used in systems that require high torque output and precision control, such as radar systems, launchers, and positioning systems. The drive's ability to handle large loads while maintaining accuracy makes it suitable for these high-stakes applications.

6. Renewable Energy
   In addition to wind turbines, the WED17 is also used in solar tracking systems, where its self-locking feature ensures that the panels remain fixed in position, even during storms or sudden changes in weather conditions.

How to Customize Double Worm Slewing Drive WED17

Customizing the WED17 Double Worm Slewing Drive involves tailoring the drive system to meet specific application requirements. There are several factors to consider when customizing the WED17:

1. Torque Requirements
   Depending on the application, the required output torque may vary. The WED17 is available in different torque configurations, and customization can involve selecting a drive with the appropriate torque capacity for the job.

2. Gear Ratio Adjustments
   Customizing the gear ratio allows for adjustments in the speed and torque of the slewing drive. Applications that require faster rotation may opt for a lower gear ratio, while those needing higher torque may select a higher ratio.

3. Sealing Options
   For applications in environments exposed to harsh conditions (e.g., extreme temperatures, humidity, or dust), sealing can be customized to ensure optimal protection for the internal components.

4. Bearing Selection
   Depending on the axial and radial load requirements, different bearing types can be chosen to increase the drive's load capacity and longevity.

5. Mounting Configurations
   The mounting dimensions and installation configuration can be customized to fit the specific machinery or platform, ensuring that the WED17 integrates seamlessly into the application.

Price Factors for the Double Worm Slewing Drive WED17

The price of the WED17 Double Worm Slewing Drive depends on several factors, including:

1. Torque Capacity
   Higher torque drives generally cost more due to the increased material and design complexity required to handle greater loads.

2. Customization Options
   Custom features such as specific gear ratios, bearing types, and sealing options will increase the price.

3. Production Volume
   Bulk orders may reduce the cost per unit, while smaller orders or one-off customizations may be more expensive due to setup and production costs.
